Pricing for popular hotel rooms can be influenced by a variety of factors, including time of year, type of room, location, room occupancy and competitive pressures. Keeping that data updated in real time can be a challenge for all reservations systems, because hotel rooms are sold on multiple travel platforms throughout the world. Without getting into the technical details of how search results are returned on the website, sometimes after the initial list of hotels are displayed, there could be a change in the price once you click on your chosen hotel to see the room type availability. The reasons why it changes can vary, but include things like network speed, inventory changes, etc. While it doesn’t happen often, we strive to provide the most accurate and up-to-date information, so you can save the most money possible.
